A 1 kilogram parcel of air is at 25 degrees Celsius and contains 14 grams of water vapor. what is the relative humidity?
Relative humidity is calculated by comparing the actual water vapor in the air to the maximum amount of water vapor the air can hold at a given temperature. At 25 degrees Celsius, the saturation vapor pressure of water is approximately 23 grams per cubic meter. Given that the parcel contains 14 grams of water vapor, the relative humidity can be calculated as (14 grams / 23 grams) × 100%, which equals approximately 60.9%.
What is specific humidity and relative humidity?
Relative humidity compares the amount of water vapour present in the air with the amount of water vapour that would be present in the same air at saturation. Specific humidity is the mass of water vapour present per kg of total air.
What is the relative humidity of 25c air that contains 10gm of water vapor show work?
To find the relative humidity of air at 25°C containing 10 grams of water vapor, we first need to determine the saturation vapor pressure at that temperature. At 25°C, the saturation vapor pressure is approximately 23.8 grams per cubic meter (g/m³). Assuming we have a volume of 1 cubic meter of air, the relative humidity can be calculated using the formula: [ \text{Relative Humidity (%)} = \left( \frac{\text{Actual Vapor Content}}{\text{Saturation Vapor Content}} \right) \times 100 ] Substituting the values: [ \text{Relative Humidity} = \left( \frac{10 , \text{g/m}^3}{23.8 , \text{g/m}^3} \right) \times 100 \approx 42.02% ] Thus, the relative humidity of the air is approximately 42%.
What is the percentage of water vapor a certain volume of air contains relative to the maximum amount?
The percentage of water vapor in a certain volume of air relative to the maximum amount it can hold is referred to as the relative humidity. It is calculated by taking the actual amount of water vapor present in the air, dividing it by the maximum amount the air can hold at that temperature, and then multiplying by 100. For instance, if the air contains 10 grams of water vapor, and the maximum capacity at that temperature is 20 grams, the relative humidity would be 50%.
What percent is 6 grams of 1000 grams?
6 grams is 0.6 percent of 1,000 grams.
If the specific humidity of air is 10 grams per kilogram and the capacity of the air is 50 grams per kilogram the relative humidity is?
Relative humidity is the ratio of specific humidity to the overall capacity. So in this case it is 10/50, or 20 percent.

Suppose a sample of air can at most hold 10 gram of water vapor what is it relative humidity?
Relative humidity is the amount of water vapor present in the air compared to the maximum amount it could hold at a specific temperature. In this case, if the air can hold at most 10 grams of water vapor and there is currently 5 grams present, the relative humidity would be 50% (5 grams / 10 grams * 100%).
What is specific humidity and relative humidity?
Relative humidity compares the amount of water vapour present in the air with the amount of water vapour that would be present in the same air at saturation. Specific humidity is the mass of water vapour present per kg of total air.
If a parcel of air is capable of holding 28 grams per cubic meter but it only contains 21 grams?
75% relative humidity.
If 4 grams of water vapor are present in a cubic meter of air that can hold a maximum of 10 grams is 40 percent?
humidity
If you had a cubic meter of air at 20 degrees C that was holding 3 grams of water what would the relative humidity be?
To calculate the relative humidity, we need the actual vapor pressure (partial pressure) of water in the air and the saturated vapor pressure at the air temperature. At 20 degrees C, the saturated vapor pressure of water is around 2.34 kPa. By converting 3 grams of water to moles and calculating its partial pressure, we can find the relative humidity is approximately 46.2%.

The amount of water vapor actually in the air is called the?
The amount of water vapor in the air is called the absolute humidity. It is usually expressed as grams of water vapor per cubic meter of air.
What is the percentage of water vapor a certain volume of air contains relative to the maximum amount?
The percentage of water vapor in a certain volume of air relative to the maximum amount it can hold is referred to as the relative humidity. It is calculated by taking the actual amount of water vapor present in the air, dividing it by the maximum amount the air can hold at that temperature, and then multiplying by 100. For instance, if the air contains 10 grams of water vapor, and the maximum capacity at that temperature is 20 grams, the relative humidity would be 50%.
How to Calculate actual humidity from relative humidity?
One can calculate the absolute humidity (AH) from the relative humidity (r) using three equations: (1) the equation for mixing ratio, (2) an equation for relative humidity expressed in terms of mixing ratio, and (3) the Clausius-Clapeyron equation, which relates saturation vapor pressure to temperature. The result of combining the three equations is: AH = (1324 r/T) [exp {5417.75 (1/273 - 1/T)}] where AH is expressed in grams per cubic meter, T is temperature in Kelvin, r is relative humidity (range is 0 to 1), and the relation holds true for T>273. For T<273, replace 5417.75 with 6139.81.
The measurement of the grams of water In a kilogram of air is called what?
The measurement of the grams of water in a kilogram of air is called "humidity," specifically expressed as "absolute humidity." Absolute humidity quantifies the actual amount of water vapor present in a given mass of air. Another related term is "specific humidity," which refers to the mass of water vapor per unit mass of air, including the water vapor itself.
